Processing

Prompted by our passion and respect for nature, we obtain our inspiration for producing superior quality speciality seed oils. Through our expertise, combined with advanced research and traditional knowledge of farming and processing, we provide plant solutions to the professionals in our industry. The majority of our processing is still based on traditional methods which are further tailored to suit each specific product. The oil is obtained either by cold pressing, where the seed is mechanically pressed on a screw press, or by solvent extraction. Further processing is tailored to suit customer requirements, whether it be virgin oil in its purest form or a colourless fully refined oil.
